Abstract (en)
[origin: US4581920A] In order to measure an ex-vivo bleeding time, a blood sample is applied on a measuring opening in a support. A pressure difference is created across the measuring opening and then time is measured during which a definite reduction of size of the measuring opening occurs due to aggregation of blood platelets.
